Abstract: PURPOSE:To reduce the influence of a detecting error and to improve the accuracy of positioning operation by calculating a positional error signal based on a forecasting value of a driving signal at the time of detecting the abnormality of a driving signal to compensate a positional error and improving the calculated value of the driving signal. CONSTITUTION:A driving signal forecasting circuit 3 finds out a driving signal value at the succeeding sample time based on a driving signal value obtained before the present sample time stored in a driving signal storage circuit 2 and outputs the found value to an output circuit 4. The output circuit 4 compares the output u'k of the circuit 3 with the output u''k of a driving signal calculating circuit 1 by using a previously specified value alpha, and when the output u''k is not satisfied with u''k-alpha<=u''k<=u'k+alpha, the output u'k of the circuit 3 is outputted to a head driving mechanism 5 and a driving signal storage circuit 2 as a driving signal uk, a positional error calculating-back circuit 8 is started on the basis of the driving signal uk to find out a positional error forecasting value e'k and the recalculation of the circuit 1 is executed by using the found value e'k as a positional error.

Title: Thermal infrared image sensor
Inventor: NOMURA HITOSHI
IPC: H04N5/33
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To enable high-sensitivity and a high-speed operation and to improve an S/N by integrating the output current of a buffer amplifier after a current component corresponding to an background light component is removed from the current signals of respective pixels. SOLUTION: The current signal consisting of a background light current signal (ID) and a current signal (IS) due to infrared radiation outputted to vertical read lines 2a-2c is inputted through the buffer amplifier and turned-on MOS transistors QD1-QD3 for switch to an integration circuit and 2nd current sources 11a-11c for each column. In this case, since a current equal with the background light current signal of a pixel 1 is outputted from the 2nd current sources 11a-11c, the background light current signal (ID) is subtracted from the resultant current signal (ID+IS) and as a result, only the current signal (IS) corresponding to temperature rise caused by infrared radiation is inputted to the integration circuit. Thus, the gain of the integration circuit can be improved regardlessly of the background light component and the S/N can be improved with high sensitivity.
